2. A fastening device of the class described comprising two elongated parts composed of resilient material, each of said parts having two series of spaced apart projecting portions and sockets, the projecting portions and sockets of one series being in staggered relation to the other series of projecting portions and sockets and in a different plane, the projecting portions and sockets of each part being adapted to interlock respectively with the sockets and projecting portions of the opposite part.

3. A fastener of the class described comprising two elongated parts composed of resilient material, each of said parts having a series of spaced interlocking projecting portions and sockets intermediate the projecting portions formed of said resilient material, and a second series 'ot'interlocking projecting portions and sockets intermediate the same also formed of said resilient material disposed in a plane parallel to but adjacent to the plane of the first series of projecting portions and sockets.

4. A fastener of the class described comprising separate parts adapted to be coupled and uncoupled, each of said parts being composed of rubber, each part having two series of interlocking projecting portions with sockets intermediate the same, the projecting portions of the first series 'being staggered relative to the projecting portions of the other series and in an adjacent parallel plane, the projecting portions on each part adapted to overlap the projecting portions and interengaged with the sockets on the opposite part.

5. A fastening device of the class described comprising two continuous elongated and interlocking parts composed of flexible material, the adjacent edges of said parts each having two series of spaced projections formed of the material of said parts inter-meshing and interlocking with corresponding series of projections on the opposite part, said series of projections on each part lying in adjacent parallel planes and the projections of one series being staggered relative to the projections of the other series, said projections being so formed as to mutually interlook when interengaged.
